I'm the IT guy for a business, and we just got AT&T Uverse as a backup to our faster cable service, as well as a block of 5 static ip addresses. On the phone, I was told that we could just get a modem, as we already have a dual wan router. When the guy installed it, he put in a NVG510 and said he had nothing in his paperwork about a modem only. I have spent all day trying to figure out how to pass traffic through the NVG510 to devices behind it with static IP's assigned. Ive been able to access the internet from the inside, but no traffic will come in. Is this even possible with this device? I've read elsewhere about sending all traffice to one device behind the NVG510, but that wont work for me as I need to have 5 IP's accessible from the public net.

You can get static IPs that connect directly to AT&T's gateway device, or you can route behind your own router using a single IP, but you can't do both.

I got my static IP config working (connected to a SonicWall firewall) but turns out the IP address range that the tech wrote down for me was wrong! when I called AT&T support he gave me a completely different range to use. so somewhere along the line I guess someone changed their mind about what range my account would use.
but yes, it is now working nicely.
